The process of producing pig iron in a blast furnace includes raw material proportioning, charging, ironmaking, and slag discharge. Raw materials are charged into the blast furnace in a specific ratio, and coke burns inside the furnace to generate high temperatures, reducing iron ore into iron. The reduction reactions within the blast furnace proceed under high temperature, producing molten pig iron and slag. This process encompasses energy consumption, material consumption, waste disposal, and environmental impacts associated with pig iron production.
